• Using a properly calibrated water quality meter, measure.the following indicator <br /> parameters:turbidity,pH,conductivity,oxidation-reduction potential(Eh),dissolved <br /> oxygen, and temperature. <br /> • Target values for the indicator parameters listed above are as follows.:pH-stabilize, <br /> conductivity-stabilize,temperature-stabilize,turbidity NTU 10 or stabilize. A value is <br /> considered to have stabilized when 3 consecutive readings taken at one-half well volume <br /> intervals are within 10%of each other(pH stabilization=0.2 pH units). <br /> • Notes on characteristics of the development water. <br /> _ • Data on the equipment and technique used for development <br /> PRECAUTIONS <br /> Refer to the site-specific Health and Safety Plan for discussion of hazards and preventive <br /> measures during well development activities. <br /> REFERENCES <br /> Fletcher G.Driscoll, 1986,"Groundwater and Wells",2nd Addition. <br /> Page 3 of 3 <br /> welLdev_SOP MONITORING WELL DEVELOPMENT February 2005 <br />
